You may remember a one-time question in mid-April asking, “How often do you currently ask people entering your home to remove their shoes?” This question was proposed by one of the Principal Investigators of the study, Greg Marcus. “We hear about the duration of droplets from coughs and sneezes hanging in the air, but then where do they go? Presumably they drop to the floor, where our shoes may pick them up and track them in. So might taking your shoes off before entering your home decrease the risk of infection?”
A total of 9,558 citizen scientists answered this question. Below is a graph illustrating how the question was answered. As we continue to learn more about how the COVID-19 virus travels, having answers to questions like this one can help power discoveries.
